On Friday, former national security adviser Michael Flynn pleaded guilty to making false statements to the FBI. However, he categorically denied ever engaging in treason.

“Such false accusations are contrary to everything I have ever done and stood for,” Flynn said, in part, in a statement.

As part of his plea deal, Flynn agreed to fully cooperate with special counsel Robert Mueller's investigation into Russian election interference and possible collusion between Russia and President Donald Trump's campaign.

On Saturday, before departing from the South Lawn for New York, Trump addressed Flynn's admission of guilt. When asked if he was worried what the former national security adviser will tell the special counsel, the president responded, “No, I’m not.”

The president added that “no collusion” has been shown and reiterated, “There’s been absolutely no collusion, so we’re very happy.”

A reporter also asked if the president will stand by Flynn, to which he said, “We'll see what happens.” He then thanked the press for their time and walked away.

Flynn is the first senior White House official to be charged in relation to Russia's alleged election meddling, and according to an NBC News source, Trump's administration was “blindsided” by his plea.
